Electro-Harmonix Voice Box Vocal Harmony Processor Vocoder | No Limit Guitar Co, Idaho Falls
The Electro-Harmonix Voice Box is a vocal harmony processor and vocoder that puts a full troupe of backup singers and classic synth-robot vocoder effects at your feet — driven entirely by your guitar or keyboard. Generate 2- to 4-part vocal harmonies keyed directly to your instrument, dial in male or female formants with the Gender Bender knob, and access nine programmable presets via dedicated footswitch. For singers, multi-instrumentalists, and performers at No Limit Guitar Co in Idaho Falls looking to take their live vocal sound to the next level, the Voice Box is a genuinely unique tool.
Product Overview
The Voice Box generates vocal harmonies by reading the pitch of your accompanying instrument — plug in a guitar or keyboard, and the processor automatically produces harmonies in the correct key without any manual pitch selection. The Low and High Harmony controls independently produce a 3rd and 5th harmony note respectively, giving you flexible 2- to 4-part harmony stacking that tracks your instrument in real time. A professional-quality pitch shifting algorithm keeps harmonies sounding natural and realistic rather than robotic or artificial.
The built-in 256-band articulate vocoder — designed by the same EMS engineer whose work made vocoding famous — delivers the classic synth-robot vocal textures that have defined records across pop, electronic, and hip-hop music for decades. Adjustable harmonic enhancement and a controllable formant shift via the Gender Bender knob allow you to shape the vocoder's character from deep and masculine to bright and feminine, giving you a wide palette of vocoder tones from a single intuitive control.
Studio-quality onboard reverb can be applied independently to your dry vocals and harmony vocals, adding depth and space to your live vocal performance without needing an external reverb unit. A built-in mic preamp with phantom power and gain switch, balanced XLR line output, and a mic bypass footswitch make the Voice Box a complete vocal processing solution that interfaces directly with any mixing board or A/D converter. For performers at an Idaho Falls guitar store who want a single pedal that handles harmony, vocoding, reverb, and mic preamp duties, the Voice Box covers all the ground.
Ideal For
- Singer-songwriters and solo performers who want instrument-driven vocal harmonies without a backing band
- Live performers seeking the best vocal harmony pedal for guitar or keyboard-driven harmony generation

Key Features
Instrument-Driven Harmony Generation The Voice Box reads the pitch of your connected guitar or keyboard and generates 2- to 4-part vocal harmonies in the same key — no manual pitch selection required, and no harmony that clashes with your playing.
256-Band Articulate Vocoder Designed by the EMS engineer whose work established the vocoder as a musical instrument, the Voice Box's 256-band vocoder delivers highly articulate, expressive synth-robot vocal effects with adjustable harmonic enhancement.
Gender Bender Formant Control The Gender Bender knob shifts the formant character of your vocal and vocoder output between male and female tonal qualities, giving you a broad range of vocal textures and timbres from a single continuous control.
Built-In Mic Preamp with Phantom Power An onboard mic preamp with phantom power and gain switch means the Voice Box can power condenser microphones directly — no external preamp required — and a balanced XLR line output connects directly to any mixing board or audio interface.
Nine Programmable Presets Nine user-accessible preset slots store your favorite harmony and vocoder configurations, each recallable via a dedicated preset footswitch for fast, reliable changes during live performance.
